Association of the severity of tongue lesions in broiler chickens with the quality of corn in feed
The objective of this work was to determine the correlation of the physical attributes of corn and the mycotoxins present in its grains with the severity of tongue lesions in broiler breeder roosters. The occurrence of the aflatoxin, vomitoxin, zearalenone, T-2 toxin, and fumonisin mycotoxins was de...

Zusammenfassung: | The objective of this work was to determine the correlation of the physical attributes of corn and the mycotoxins present in its grains with the severity of tongue lesions in broiler breeder roosters. The occurrence of the aflatoxin, vomitoxin, zearalenone, T-2 toxin, and fumonisin mycotoxins was detected in the corn grains used in the feed formulation for breeder chickens. The percentages of moisture and broken grains were positively correlated (Pearson’s correlation) with the presence of aflatoxin. Milder lesions (grade 1) are positively correlated with aflatoxin and negatively correlated with fumonisin, and the most severe lesions (grade 3) are positively correlated with vomitoxin, fumonisin, and T-2 toxin.
Resumo: O objetivo deste trabalho foi determinar a correlação entre os atributos físicos do milho e as micotoxinas presentes nos seus grãos com o grau de lesão de língua em galos reprodutores de corte. Verificou-se a ocorrência das micotoxinas aflatoxina, vomitoxina, zearalenona, toxina T-2 e fumonisina em grãos de milho usados na formulação da ração das aves reprodutoras. Os percentuais de umidade e grãos quebrados foram positivamente correlacionados (correlação de Pearson) com a presença de aflatoxina. As lesões mais suaves (grau 1) correlacionam-se positivamente com aflatoxina e negativamente com fumonisina, e as mais severas (grau 3) estão positivamente correlacionadas com vomitoxina, fumonisina e toxina T-2. |
